Astronomy 101 2023-2024 Exam Questions with All Correct Answers According to our present theory of solar system formation, how did Earth end up with enough water to make oceans? - Answer-The water was brought to the forming Earth by planetesimals that accreted beyond the orbit of Mars. The terrestrial planets in our solar system are: - Answer-Mercury, Venus, Earth, and Mars. The jovian planets in our solar system are: - Answer-Jupiter, Saturn, Uranus, and Neptune.

The earth is made mostly of rocky material and metals such as iron, whereas jupiter is motly hydrogen and helium. What is the main reason that Earth's composition is different from Jupiter's? Compared to Jupiter, Earth formed in a hotter region, where only rocks and metals could exist as solids most planets fall into one of two catergories in terms of composition. How would you best define these categories? Planets that are mostly rock and metal versus those that have a lot of H and HE How d...

A THEORY is a pattern in nature thought to have predictive power. The test of a theory is a prediction. That's where pseudo-science fails. T/F - Answer-T Red giant stars are powered by hydrogen burning in a shell surrounding a core, which has been depleted of hydrogen. T/F - Answer-T Jovian planets have densities similar to that of water, and we know in fact that they are mostly made of water. T/F - Answer-F - Jovian planets are gaseous The Sun appears to circle the Celestial Sphere in on...

-- Life, orbital resonances, rings and gaps. - ️️Give three examples of current properties of the solar system that a model of its formation need not explain. Why? 11. How did the temperature structure of the solar nebula affect the planetary composition? - ️️-- The distance between a planet and the sun determines the temperatures at which each planet was created. For planets close to the Sun like Mercury and Venus, the temperature was too high for those planets to be formed with light ...

Nearly spherical 3. Cleared it's orbit of debris Zone 1 of the Solar System correct answers First four planets, terrestrial (rocky), small Zone 1.5 of the Solar System correct answers Asteroid belt lies betwe...

Astronomy 105 - Chapter 8 Exam Questions Correctly Answered. The following images show Earth and the four jovian planets of our solar system. Rank these planets from left to right based on their distance from the Sun, from closest to farthest. (Not to scale.) - CORRECT ANSWER Earth, Jupiter, Saturn, Uranus, Neptune The following images show Earth and the four jovian planets of our solar system. Rank these planets from left to right based on their size (average equatorial radius), from smal...

Astronomy 101 Chapter 8; Mastering Astronomy Assignment Review Practice Test. Observations show that interstellar clouds can have almost any shape and, if they are rotating at all, their rotation is not perceptible. However, the nebular theory predicts that a cloud will rotate rapidly once it shrinks to a relatively small size. What physical law explains why a collapsed cloud will rotate rapidly? - CORRECT ANSWER the law of conservation of angular momentum The nebular theory also predicts ...

A feature of the Jovian planets is that _________. - ️️They are composed primarily of hydrogen Analemma - ️️The figure-8 path traced by the Sun over the course of a year when viewed at the same place and the same time each day. Represents discrepancies between apparent and mean solar time. Annual Trigonometric Parallax - ️️ Annular Eclipse - ️️Solar eclipse during which the Moon is directly in front of the Sun but its angular size is not large enough to fully block the Sun Ar...

A convex lens is thinnest in its center; it refracts light to a focus, while a convex mirror reflects it to the focus instead. T/F - ️️False A lunar eclipse can only happen during a: - ️️Full Moon A mountain top is an especially good site for infrared telescopes since: there you are closer to celestial objects. -you are above most of the carbon dioxide and water vapor in the atmosphere. -the cold weather helps the sensitivity of infrared detectors. -less air above means better se...
